Abstract (en)

[origin: US2020011605A1] Manufacturing a heat exchanger by brazing of multiple heat transfer pipes, multiple fins, and headers. The multiple heat transfer pipes joined to each fin with the heat transfer pipes each being inserted into cutout recessed portions as cutouts of side portions of the fins on one side. The headers each joined to both end portions of each heat transfer pipe to couple the multiple heat transfer pipes and having internal spaces for collecting or distributing fluid flowing in the multiple heat transfer pipes. A protruding length Tf of each fin from a corresponding one of the heat transfer pipes and a distance Th from each heat transfer pipe to an outer surface of a corresponding one of the headers on the same side as a protrusion are substantially equal to each other.
